Solar System

Mercury

The closest of the planets to the Sun and somewhat near to Earth, it is visible to observers on Earth in the late evening or early morning sky. This planet is also reffered as morning star and evening star for the reason. This is because Mercury shines brightly in the early morning just before the sun rises and is also visible for a brief period of time just after the Sun sets.

Mercury has less gravity so if you moved to Mercury you would not weigh as much as you did on Earth, because Mercury is smaller. Assuming you weigh 70 lbs (32 kg) on Earth, you would weigh only about 27 lbs (12 kg) on Mercury.
